Worked on backend reliability for the openclaw/openclaw repository by addressing a startup race condition in the gateway component. Implemented a synchronization mechanism in Node.js and TypeScript to ensure ACP messages are processed only after the gateway is fully ready. The solution required modifying the gateway’s startup sequence to wait for a ‘hello’ confirmation from AgentSideConnection before handling incoming messages, thereby preventing premature processing and potential errors. This targeted bug fix improved system reliability and messaging correctness during initialization, reducing downtime and error rates. The work demonstrated a focused approach to backend development and concurrency control using TypeScript.
